Kanji Encounter
Read full descriptionHide full description
Kanji Encounter teaches the first fifty kanji the way you actually meet them: inside a conversation. Mia has just arrived at her host grandmother's house in Japan. Sora the cat is asleep in a basket. Every lesson is a short exchange between the three of them, and somewhere in it sits a character you have not met before — with furigana above it, an English line below, and romaji if you want it. Then it comes back. Days later, the same kanji turns up inside a different word, and its reading has changed. "日" becomes "日曜日". "時" and "間" become "時間". The app stops and shows you what just happened, because that moment makes kanji feel like meaning rather than shapes. WHAT A DAY LOOKS LIKE - Learning 3 new kanji is your daily goal — once you hit it, you can keep learning a few more at a time. - Reviews return on their own schedule, spacing out as you get them right. - A short guess after a lesson — can you read this? It never counts against you. - Every character you have met grows a tree of the words it appears in. FIFTY KANJI, FIFTY PICTURES Each character has its own watercolour illustration, drawn for this app. WHAT IS NOT HERE - No account. Nothing to sign up for, nothing to remember. - No ads, no tracking. - No backend of ours. The only network traffic is the subscription check. FREE AND PAID Chapter one — ten kanji, ten conversations — is free. Chapters two to four unlock with Full Access. SUBSCRIPTION Full Access, USD 2.99 per month, auto-renewing until cancelled.

Verdict
The clearest difference is update cadence: Kanji Encounter at every 5 days against iKnow!'s every 5 weeks. iKnow!'s advantage is device support (4 vs 1) and iOS requirement (14.0 vs 16.4). On price, ads and in-app purchases there is nothing between them.
